abstract：:As sperm traverse the female tract from vagina to oocyte, they experience a steroid milieu, which due to transcriptional inactivity, they can only respond to via non-genomic signaling. This environment mediates events including capacitation, changes in motility patterns, chemotaxis, and acrosome reaction. Current know...
